Physics - NLM Question with Solution | TestHub

A cylinder of mass 10 kg is resting between two frictionless inclined surfaces AB and AC, and is attached to a vertical string PQ whose other end Q is fixed to the ceiling as shown in figure. If forces, cylinder applies to surface AC and AB are 30 N and 40 N respectively, the tension in the string is [ $\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2$ ]
